sandhopper การใช้

• Sandhoppers use the sun daily to determine where their home lays.
• Then, the sandhoppers were placed on the beach in natural sunlight.
• With this experiment a group of sandhoppers were subjected to six hours of artificial lights and their movements were monitored when exposed to normal sunlight.
• Sandhoppers ( such as " Talitrus saltator ", also called sand fleas ) are small shrimp-like crustaceans that live on beaches.
• The sandhopper's orientation when finally exposed to normal sunlight, showed that their orientation was off by 90 degrees when in respect to their home.
• When sandhoppers ( such as " Talitrus saltator " ) are taken up a beach, they easily find their way back down to the sea.
• A group of sandhoppers were acclimatised to a day / night cycle under artificial lighting, whose timing was gradually changed until it was 12 hours out of phase with the natural cycle.
• The experiment implied that the sandhoppers use the sun and their internal clock to determine their heading, and that they had learnt the actual direction down to the sea on their particular beach.
